Expedia, Travelocity and a number of other travel information websites have joined to oppose Google's proposed $700 million acquisition of ITA.

ITA provides travel related information, such as airline ticket prices, seating and flight details to third party travel firms.

Travelocity, TripAdvisor, Expedia, Sabre Holdings and several other online travel companies have formed the FairSearch.org alliance to prevent Google from acquiring ITA. They fear that the acquisition will harm the market competition and increase the prices for customers.

In a blog post FairSearch.org said: “Google’s announcement on July 1st that it intends to purchase ITA Software, presents a threat to competition and transparency in online travel search and could lead to higher travel prices and less choice for consumers.”

Meanwhile, The Wall Street Journal reported that FairSearch.org is urging the US Department of Justice to look into Google's acquisition of ITA.

Google has said that acquisition will not have on impact on the existing market share and that the company will continue to honour all the existing agreements ITA has with travel search companies.
